Due to the exceptionally high safety requirements in regard of changing filter elements in nuclear facilities, bio-safety laboratories and other environments with high risk for staff, people and environment, a "safe change" procedure will be used when changing filter elements, utilizing the Krantz heat sealing device HS-D hightec.

Information:

The Krantz heat sealing device HS-D hightec combines

•ease of handling by low weight device, completely removable upper sealing bar and automatic process

•consistent pressure over the seal length (patent pending)

•guaranteed process parameters

•documentation of sealing process

•quality and consistency of sealing (20% improvement versus conventional sealing, confirmed by third party approval)

Krantz sealing device HS-D hightec is used in nuclear industry and safety laboratories for many years.

Features:

•1,000 mm wide welding device, suitable for bag-in bag-out procedure of pre-filters and HEPA-filters with dimensions up to 610 x 610 x 292 mm

•Constant and regular pressurization of the sealing area

•Permanent temperature control of each sealing strip by means of thermocouple

•Electronic microprocessor control for all relevant and pre-set sealing parameters (pressure, time, temperature)

•Sealing and cutting of plastic bag in one process

•Each side of the plastic bag double-closed by two seals, cut in the middle of the intermediate seal

•Documentation of sealing history (full data set including temperature graphs for the last 10 seals, reduced data set for 999 seals)

•Possibility of displaying, printing and storing all sealing history by using the PC software

•Predefined sealing parameters set to Krantz PE plastic bags

•Complete delivery of sealing device with power generator, PC software and one set of ware parts (PTFE protective cloth and sealing stripes)
